Q

Outline the effect of energy balance on performance

A

• Energy balance is achieved when the energy we consume matches the energy we expend during exercise (energy intake = energy expenditure)

• If we over-consume food compared to the energy we expend (calorie surplus) we achieve positive energy balance
• If we under-consume food compared to the energy we expend (calorie deficit) we achieve negative energy balance

• If performers don’t meet energy demands during training periods it can result in:
-Muscle atrophy
-Decreased intensity and duration of performance
-Slow recovery rates
-Increased risk of injury, fatigue and illness

• So weight-loss plans should be scheduled into training plans away from heavy training/competition

Q

Outline the effect of optimum weight on performance

A

• Different sports require differing optimal weights and manipulation of diet can be used to achieve this

• This can be applied within sports, e.g. boxers trying to make a weight category (increasing/decreasing weight), a sumo wrestler trying to be as heavy as possible or a cyclist trying to be light to find an optimal power:weight ratio

Q

Explain how calorie requirements are calculated

A

BMR + METs + Thermic effect = Total caloric req.

• BMR = Basal metabolic rate; the ratio of a performers working metabolic rate relative to their resting metabolic rate

• METs (metabolic equivalent tasks) calculate the energy expenditure of a physical activity, using oxygen per unit of body weight per minute to measure exercise intensity (ml/O2/kg/min)

• Thermic effect = Energy required to eat, digest and absorb food

Q

Outline different types of sports drinks

A

• Hypotonic solutions (4% glucose):
-Glucose osmolality is lower than in the blood
stream, so replaces fluids lost by sweating,
providing small amounts of glucose for energy.
-Used by athletes for hydration without energy
boosts such as jockeys and gymnasts

• Isotonic solutions (5-8% glucose):
-Glucose osmolality is the same as in the
bloodstream, so it’s absorbed at the same rate
as water and is quick to rehydrate and provide
energy.
-Used by middle to long distance athletes and
games players

• Hypertonic solutions (8%+ glucose):
-Glucose osmolality is higher than the
bloodstream so they’re absorbed slower than
water, consumed pre or post exercise
-Predominately consumed post exercise to
maximise glycogen replenishment (fluid
replenishment is secondary)

Q

Outline and evaluate creatine as a contemporary supplement

A

• A compound the body makes naturally that supplies energy for muscle contraction, it can also be used as a supplement to increase performance by increasing phosphocreatine stored in the muscles

+ PC’s used to fuel the ATP-PC system which
provides energy, increasing creatine in muscles
allows this energy system to last longer and
perform at a higher intensity for longer
+ Helps improve recovery times

-Muscle cramps, diarrhoea, water retention,
bloating, vomiting as it makes muscles retain
more water
-Hinders aerobic performance
-Mixed evidence to show the benefits

Q

Identify strategies of optimal food intake for a strength athlete (including pre- and post-physical activity)

A

• General diet includes 5-6 meals a day including:
• 30% (1.8g/kg bodyweight) lean protein for
muscle growth and repair
• Complex carbohydrates to release energy
slowly, control blood glucose levels and
reduce fat storage
• Limited fat intake for energy and hormone
production

• Pre-physical activity: Small meal with equal
quantities of high GI carbs and protein 20-60
minutes before

• Post-physical activity: High GI carbs and protein
to be digested as soon as possible after exercise
(within 2 hours) to replace glycogen stores and
promote protein synthesis for muscle/strength
gain

Q

Identify strategies of optimal food intake for a endurance athlete pre-, during and post-physical activity

A

• Pre-physical activity:
• Slow digesting carbohydrate meal 3 hours
before (1.4g/kg bodyweight) or low GI
carbohydrates to maximise glycogen stores
• Simple carbs and high GI foods half hour
before to top up glycogen stores and maintain
blood glucose levels

• During physical activity (longer than 1 hour):
small amounts (30/60g) of fast digesting
carbohydrates to maintain blood glucose and
saturate muscle glycogen stores

• Post-physical activity: 1-1.5g per kg of
bodyweight of carbohydrates per hour within
30min of the event, every 2hours for the next 6
hours. Moderate to fast digesting carbohydrates
promote faster recovery

Q

Outline the window of opportunity as a strategy for optimal food intake

A

• After exercise, our muscles are primed to accept nutrition that stimulates muscle repair, growth and strength

• Within the first 30 minutes an athlete should aim to consume high GI carbohydrates to initiate replenishment of glycogen stores and maintain electrolyte balance
• While protein synthesis persists for at least 48 hours after exercise, it’s most important to consume lost exercise nutrition immediately (within 2 hours)

• Failing to provide lost-exercise nutrition fast enough decreases muscle glycogen storage and protein synthesis, even if it’s only by a few hours

Q

Outline and evaluate glycogen loading as a strategy for optimal food intake

A

• Athletes alter their carbohydrate intake in the week before an event to maximise glycogen stores in the muscles and liver, split into three phases:
• Depletion phase (first 3-4 days): Low carb diet
and continuation of exercise
• Repletion phase: Taper training and eat a high
carb diet
• Super-compensation phase (days 5-7): Due to
biological stress, reduction in carb stores due to
training when replenishing, the body’s forced to
store more glycogen

+ Increased glycogen stores
+ Increased endurance capacity: delays fatigue
and increases time to exhaustion by up to 30%

-Hypoglycaemia and poor recovery rates in the
depletion phase
-Lethargy and irritability, affects mental
preparation
- Increased injury risk and gastrointestinal
problems

• The relevance of the choice of exercise to the athletes activity being improved. Focuses on the most appropriate way to develop the required components of fitness for the sport/position and where possible match the activity

• Factors affecting specificity include the contribution of energy systems, important components of fitness, muscle fibre types, skills and movements required in the sport/position

82
Q

Outline the difference between individual needs and specificity as principles of training

A

Individual needs focuses on the person/individual while specificity focuses on the sport/activity/position

83
Q

Outline progressive overload as a principle of training

A

• The need to increase training demands on the body, in order to encourage it to adapt further

• ‘More than normal’ gradually working with more intensity throughly the training programme to adapt to incremental training demands, improving fitness levels safely and reducing injury risk

• This can be achieved through the FITT principles, that can be manipulated to meet both specificity and progressive overload
• Frequency: ‘How often’ a performer trains

• Intensity: ‘How hard’ can be manipulated by
changing the length of the session, increasing
resistance, modifying work:relief ratios. Should
be specific to the activity (training zones)

• Time: ‘How long’ training duration- specific to
the aims of the sport

• Type: ‘The method’ and type of training: what
exercise should be specific to the aims of the
sport (matching) but will vary depending on the
periodised year

84
Q

Outline overtraining as a principle of training

A

• Occurs when intensity of volume of training are increased to extreme levels and there’s a lack of recovery within or between training sessions

• Doesn’t allow enough time for the repair of micro tears or the replenishment of energy stores, which could ultimately lead to fatigue, causing illness and/or injury

85
Q

Outline reversibility as a principle of training

A

• When training loads are reduced or removed completely, the state of fitness for performance returns to normal training state

• ‘Use it or lose it’. Adaptations gained through regular and progressive training will be lost if training at appropriate levels are not maintained. This generally occurs if athletes are ill/ injured for any period.
• For this reason, health and fitness experts are not in favour of ‘total rest’ and some form of ‘optimal exercise’ should be done in the recovery phase

86
Q

Outline how can we measure working intensity

A

• Intensity can be measured through scientific, lab based testing (e.g. blood lactate/gas analysis) or field based methods, such as:
• Target heart rate
• Rating of perceived exertion (RPE)
• Work:Relief ratios
• Calculating 1RM

87
Q

Outline the use of target heart rate as a way of measuring and calculating working intensity

A

• Target HR can be found by finding maximum HR (220-age) and multiplying it by the training percentage (aerobic zone= 60-80% of max HR/ anaerobic zone = 80-90% of max HR)
• 220 - age = max HR
• Max HR x training percentage = Target HR zone

• Karvonen’s theory (more accurate)
• Max HR - Resting HR = HR Reserve
• (HR reserve x training %) + Resting HR = Target
HR zone

• Percentage of functional threshold is the HR sustained for a one hour race effort to establish training zones. Functional threshold can be determined by a 30min full effort test with average heart rate of the last 20minutes used to determine intensity

88
Q

Outline the use of Rating of Perceived Exertion (RPE) as a way of measuring and calculating working intensity

A

• The Borg scale is a universal method of measuring physical activity intensity level of a scale of 6-20. It’s a subjective perspective on how hard you feel your body’s working based on physical sensations during exercise such as increased HR, breathing rate, sweating and muscle fatigue

89
Q

Outline the use of Work : Relief ratios as a way of measuring and calculating working intensity

A

• Used as a method to calculate exercise intensity by controlling duration of activity compared to the rest during interval training. They allow for the recovery of energy systems while resting (e.g. a work:relief ratio of 2:1 means the effort is twice as long as the rest

90
Q

Outline how altering Work : Relief ratios targets different systems

A

ATP/PC system (e.g. 1:3)
• To improve speed; work ratio may be less than
10 seconds while the relief ratio’s normally
longer allowing time for ATP and PC stores to
fully recover (2-3 minutes)

Glycolytic System
• To improve anaerobic endurance (increased
resistance to lactate accumulation) the work
ratio’s less than 10 seconds but with a shorter
relief period (e.g. 1:2 so only (e.g.) 50% of ATP/
PC restoration) or a longer work period,
increasing lactate accumulation, overloading the
lactic acid system

Aerobic Glycolytic
• To improve Vo2 max using submaximal
exercise. The work:relief ratio is normally longer
in duration and the intensity is just below
anaerobic threshold. The relief ratio’s typically
shorter (1:1) which helps reduce OBLA and
delay muscle fatigue and therefore prolong the
aerobic systems adaptations

91
Q

Outline the use of calculating percentage of 1RM as a way of measuring and calculating working intensity

A

• Used as a method to calculate exercise intensity by controlling training load. Different resistance goals are based on different percentages of 1 rep max

• Muscular endurance (60%)
• Muscular hypertrophy (70-85%)
• Strength (85+%)

92
Q

A

• Fitness trackers
• GPS
• Fitness machines
• Power meters
• Laser sensor equipment
• Wind tunnels
• Technology and drag
• Force plates
• Video analysis/software
• Bat sensors
• Isokinetic strength training machines

93
Q

Outline fitness trackers as a contemporary technology to monitor fitness and performance

A

• Heart rate monitors and pedometers are still used, but the evolution of fitness trackers and smart wrist bands have combined both and added extra data, such as distance, calories used, steps and monitor sleep

• Heart rate monitors allow performers to make
sure they’re in a target HR zone, they’re less
accurate in sudden short efforts and with high
intensity anaerobic activity.
• They’re an ageing technology and most sports
watches have GPS technology and associated
mobile apps that calculate trading intensity
based on age, weight, height, gender and can
accurately track calorie burn and distance run
(including splits and store data and compare it
on performance graphs)

• Pedometers detect the impact between the foot
and ground that causes the body to accelerate/
decelerate, it’s an internal device detecting
position change and count the number of
footfalls during activity, contemporary
pedometers can track footballs, distance run
and energy output using GPS technology.
They’re used to assess stride length/cadence
and total energy output

94
Q

Outline GPS’ as a contemporary technology to monitor fitness and performance

A

• Commonly used in teamsports, GPS devices can monitor distance moved, speed, acceleration and HR in real time. They’re becoming more affordable now but are almost replicated by modern HR monitors

• Devices can be worn during games and data is received remotely. This data can be used to assess and manage workloads to develop areas of weakness, coaches can understand players psychological limitations and they can be used for tactical changes

95
Q

Outline fitness machines as a contemporary technology to monitor fitness and performance

A

• Can monitor heart rate and give information on aerobic performance as most commercial gym equipment is computerised

• E.g. cycle ergometer, treadmill, stepper, cross trainer

96
Q

Outline power metres as a contemporary technology to monitor fitness and performance

A

• Measures training intensity by using a strain gauge for rowers and cyclists. Knowing power output is a quantitative, replicable way of assessing how hard a performer is working and when it’s time to rest between bouts of exercise

• Power data can be used by coaches to accurately determine the performance requirements of an event. They measure training intensity very accurately but are very expensive

97
Q

Outline laser sensor equipment as a contemporary technology to monitor fitness and performance

A

Assesses speed of a performers during sports such as the long or triple jump, ski racing or Formula One

98
Q

Outline wind tunnels as a contemporary technology to monitor fitness and performance

A

• Used to assess aerodynamics to improve the flow of fluid and reduce drag/fluid friction of objects such as bikes, cycle helmets and a cyclists overall profile

• Air is blasted last the stationary object in a tunnel and smoke is used to illustrate the layers of flow of air. The task is to avoid vortex generation in the air flow because a laminar (smooth) flow generates less drag

99
Q

Outline technology and drag as contemporary technology to monitor fitness and performance

A

• Computer programmes show how adjustments to shape can be made before construction, reducing expense and making the shape-making process more systematic
• This can apply to cycling, rowing, kayaking, bobsleigh, luge, skeleton, speed skating including the helmet costume and body angle

• Further application of the technology can be used to increase drag to improve propulsion in water-based activity through improved patterns of pulling in swimming and shape of blades in rowing and canoeing

100
Q

Outline force plates as a contemporary technology to monitor fitness and performance

A

• Inserted into the ground at take off area for the long/high jump or in the track space immediately after the sprint start to produce force patterns made by feet striking the plate

• This information can be combined with video footage of the same footfall to help a coach decide if changes in posture are required as the coach can tell the precise way in which the foot is active

101
Q

Outline video analysis as a contemporary technology to monitor fitness and performance

A

Software such as Quintic or Dartfish have drawing tools and playback options that can be used to assess the need for technical improvement

102
Q

Outline bat sensors as a contemporary technology to monitor fitness and performance

A

• Placed at the top of a cricket bat to measure; back lift, follow through angle, bat speed at impact, 3D swing and plane path

• Used to calculate shot timing and efficiency and correlate data with Hawkeye to see the shots efficacy and how it can be improved

• E.g. Intel-powered Speculur/ Stancebeam

103
Q

Outline isokinetic strength training machines as a contemporary technology to monitor fitness and performance

A

• Expensive, computerised, workload-controlled, strength assessment laboratory machines that provide accurate assessments of the rate of force development, force of concentration at different angles of hinge joins such as the knee or elbow

• Ideal for maximal strength and muscular endurance testing

• E.g. The Lido isokinetic machine is used to compare strength ratio between antagonistic muscle pairs e.g. quadriceps and hamstring groups’ optimal strength ratio should be 2:1 for optimal performance, otherwise muscle pulls and tears could occur, particularly in the weaker hamstring group

107
Q

Outline periodisation

A

• A method of training which varies training intensity cyclically. It organises training into periods and cycles that can take place over months and years

• We periodise training to/for:
1. Manage training load and ensures players
don’t burn out or suffer from overtraining
2. Manage injury by managing training load
around competition, reducing chances of
training induced injury, ensuring players spend
more time in competition
3. Training variety by programming training into
meso and micro cycles, each cycle can have a
different focus so that different goals can be
attained

108
Q

Explain the stages of a periodised training plan

A

Periodised programmes are split into three phases:

• Macrocycles are the largest phase and last between a couple of months to a whole calendar year

• Mesocycles are a smaller phase that can last 4-6 weeks that will have a particular focus (e.g. strength)

• Microcycles divide the mesocycle into smaller components, typically lasting a week and include the basic repetitive cycle of activities

109
Q

Explain the stages of a training year

A

There are important phases within the training year that affect how a programme is periodised:

• Preparation phase: the meso and micro cycles are designed to physically prepare the athlete for the ensuing competition phase. It contains pre-season and the most physically demanding training.
• The preparation phase is broken into two stages: the general preparation phase is a generic stage at the beginning before individual needs are accounted for in the specific preparation phase

• Competition phase: Meso and microcycles are manipulated to maintain fitness levels to ensure that the athlete is in peak condition for performance. Training is predominantly focused on skill development

• Transition phase: The ‘off-season’ and pre-preparation phase where the predominant focus is on recovering from the competition phase in anticipation of moving into the next macrocycle. It often contains light cardiovascular work

• Peaking and Tapering: In order for athletes to be ready for their competition (weekly match) their training intensity is tapered (decreased) the closer they get to competitions, so they can peak for performance.
• Some coaches will identify important games in the competition phase so training intensity in the weeks leading up to that fixture will be high, before tapering in the penultimate week

110
Q

Identify and describe an alternative example of periodisation

A

• Double periodised year: the second half of the year begins the process of structure towards a second competitive period

• Research has shown this can initiate greater progress in various indicators including speed, strength and endurance
